The biggest problem people run into with 3GP files now is sound that’s missing, usually because the AMR codec isn’t supported by newer players or editors, causing them to decode only the video while ignoring the audio track, which makes it look like the sound has disappeared when it’s actually being blocked.

Another significant factor is the shift toward universal formats, replacing the fragmented early mobile era where varied networks required unique file types; with MP4 offering strong support and versatility, 3GPP2 adds no benefit and remains mainly in legacy phone backups, MMS records, voicemail databases, and regulated archives that keep original formats for authenticity.
Saying 3GPP2 emphasizes tiny file sizes and reliable operation over visual fidelity points to a purposeful engineering compromise made because early CDMA phones had limited memory, slow processors, and unreliable bandwidth, requiring heavy compression, low resolution, and speech-only audio to guarantee recording, sending, and playback, though this now shows as pixelation and detail loss on current high-resolution devices.
Reliability was equally important as minimizing file size, so 3GPP2 included mechanisms to stay synchronized despite delays, ensuring playback continued even when conditions were rough, making a functioning low-quality video far more valuable than a failing high-quality one, which is why the format—although crude by modern standards—still appears in archives due to its durability and readability.
